Spatial division multiplexing optical mode converter

摘要

Embodiments provide an optical device that includes a star coupler, a polarization bam splitter (PBS) and a polarization rotator. The star coupler includes a port at a first end face. The polarization beam splitter is optically coupled via a first side to the star coupler port, and is further optically coupled via a second side to a first port of an optical coupler. The polarization rotator is optically coupled between the polarization beam splitter and a second port of the optical coupler.
